Process
Step 1: Stamping Molding
Molds the metal surface to form the design.
Step 2: Outline Cutting
- Cutting molds are made separately, then cut to the exact outline of the design.
- Additional outline cutting molds may be required depending on the complexity of the design. * If a center hole or cut-out is required, an additional cut-through mold must be used.
Step 3: Attachment
Solder attachment onto the back of each piece.
Step 4: Plating
Plating now can be processed. The quality of plating varies with the length of time the metal is soaked in the plating liquid.
Step 5: Polishing
The metal surface is then polished until it is smooth and shiny. This applies to copper material only. Iron can be polished if required, but this will incur a surcharge.
Step 6: Coloring
- Soft enamel is carefully inserted by hand, one color at a time, using different sized syringes. * Drying. * To prevent defects, a high degree of skill is required in order to keep each color and the correct amount of enamel in the proper area.
Step 7: Cleaning
Excess color and impurities are then wiped off the metal surfaces.
Step 8: Baking
The metal piece is baked at approximately 450F for12 to 15 minutes.
Step 9: Epoxy Coating
Clear epoxy is then applied to the surface to protect the enamel from color fading and cracking. (Epoxy coating is optional and provided according to customer’s requirements)
- The standard colors are based on the Pantone Chart.
- Bolder designs are recommended in order to prevent any unsatisfactory coloring caused by lines and figures that are too thin or too small.
- General enamel coloring requires a surrounding metal space to ensure good quality painting results. Therefore it is usually necessary to allow for a blank metal rim (0.3mm minimum).
For budget considerations, iron material can be used instead of copper, but without polishing.

Famous quotes containing the word process:
“The American, if he has a spark of national feeling, will be humiliated by the very prospect of a foreigner’s visit to Congress—these, for the most part, illiterate hacks whose fancy vests are spotted with gravy, and whose speeches, hypocritical, unctuous, and slovenly, are spotted also with the gravy of political patronage, these persons are a reflection on the democratic process rather than of it; they expose it in its process rather than of it; they expose it in its underwear.”
—Mary McCarthy (1912–1989)
“By Modernism I mean the positive rejection of the past and the blind belief in the process of change, in novelty for its own sake, in the idea that progress through time equates with cultural progress; in the cult of individuality, originality and self-expression.”
—Dan Cruickshank (b. 1949)
“Yet I doubt not through the ages one increasing purpose runs,
And the thoughts of men are widened with the process of the suns.”
—Alfred Tennyson (1809–1892)
